VIDEO: Penn State's Anthony Zettel ends dance with nearly-lethal roundhouse kick

Freshman running back Saquon Barkley needs to keep his head on a swivel around a teammate like Anthony Zettel.

After showing off his dance moves in the locker room, Penn State defensive tackle Zettel pulled off a finishing move with a spinning kick ... which almost finished off Barkley with a water bottle.

Great reflexes, Saquon.
